How Can i show BW of my serial interface (cisco)

Open a terminal session to the router. Enter enable mode and
do sh int serial(Interface Number)
The band width should show up on a line similar to this
DSU mode 0, bandwidth 44210, real bandwidth 44210, scramble 0
This is for a DS3 so don't go by my numbers.
do sh int serial(Interface Number)

Are you wanting to see what the bandwidth is configured for or what the bandwidth (throughput) is on the interface?
If you have an internal CSU/DSU then you can look at the config in the Controller by checking the number of timeslots configured. Each time slot is 64k. If you have a service module then you can check there too.
Some basic commands
sh run
-then scroll down till you find the controller details
sh serv
-this will show the service module details, will also show the errors, los, lof, ais, and remote alarms
sh int s0
-this can be used to see the throughput on the interface. you will scroll down to the input and output, add the 2 together and that will give the throughput. It is also possible that when the interface was configured that it was given the bandwidth statement, although this does not mean it really is the real bandwidth, but instead that statement is used for calculating metrics to help determine routing by some protocols, like eigrp if there are more than one connections to use.
